Letters Patent No. 98,071, dated December 21, 1869.

IMPROVED FLOOD-GATE.

The Schedule referred to in these Letters P atent and makin'g part ofthe same.

To all whom it .may concern:

Be it known that I, ABRAHAM L. Kme, of Farmers- Ville, in the county ot'Montgomery, in the State cf l Ohio, have invented a new and usefulImprovement in Flood-Gates; `and I do hereby declare thatthe followingis a full and exact description thereof', reference heilig had to theaccompanying drawings,.and to tbe letters of reference marked thereon.

Figure 1 represents a front View of my improved flood-gate, and

Figure 2 represents a side elevation of the frame thereof.

In the drawings, the gates a a vare hung in the frame b b bb by thepivoted posts c c,lthe ends ot' which are inserted in circularvholes,formed in the two pieces b b of the gate-trame. i

Each gate a has connected to its front side an upright bolt, (l, ot'wood, having a wooden float, e, attached to it.

The gate-traine b bis mortised into sills f, which are designed to besunk into the ground slightly, and

braces may be used to extend from sills f to the two side pieces orposts b b ot' the gate-f`rame.

The posts b b are mortised 'into the sills f, and stand at an angle ofseveral degrees toa perpendicular line, as indica-ted by dotted line x,seen in iig. 2.

The frame b b b 1 1, with the gates a a, is intended to be set in astream of water, which may tlow through farms or enclosed lands, and inthe line of a fence, to prevent animals from passing to or from theenclosure.

The arrow A indicates the directionvof the ow of water, which will passlthrough the gates, and also shows that the frame andl gates standinclining up the stream.

lWheneve1"t11e waterin the stream rises to suticient height-to cause thefloats e to be elevated, the etect will be to raise the bolts l cl outof the mortises in )vbich their lower ends rest in the frame-piece-b,when the gates will be opened by the pressing current of descendingwater. But when the water subsides, the gates, being hung at a slight.angle to the vertical line, they will swing around, and close togetherby their gravity, and the bolts d (l will ret-urn to their mortises inframe-piece b,by sliding up inclined planes, formed on .the upper rearside of piece l1', in rea-r of the mortises, into which the lower endsor' the bolts d fall and rest, to fasten the gates in a closed position,until another ood rises in the stream in which the gate may be placed.

It will be seen that my improved dood-gates will be opened by the risingwater, yand will close themselves, and become fastened by the falling ofsame.

Also, that the entire frameway, in which the gates are hung, has no xedcentral post, orother obst-ruction, to prevent the free passage of waterand Hoodwood, which may be carried along by thefstream.

To prevent the gates from standing opened7 studs may be fixed in theframe, to prevent the gates swinging around too far. I

'I deem my present invention-an improvement upon my flood-gate, patentedMarch 16, 1869. Having fully described my invention, What I claim, anddesire to secure by Letters Iatent isfhe combination of gates a a,provided with floats e and bolts d, arranged in the inclined frames bb',and

operating in the manner and for the purpose sub- 1 stantia-lly asspecified.

In testimony whereof, I have hereunto set my hand, 4

this 13th day of' May, A. D. 1869.
